BUSH-HAMMER FOR THE BUSHING AND CUTTING OF GRANITE.

Specification of Letters Patent. patenflgd E 70. 2.5, 1913,

Application filed March 4, 1912. Serial No. 681,672.

To all whom it may concern:

Be it known that I, IRA LEMUEL DELANO, a citizen of the United States,residing at Rocklin, in the county of Placer and State of California,have invented a new and useful Bush-Hammer for the Bushing and Cuttingof Granite, of which the following is a specification.

My invention relates to improvements in bush-hammers in which cuttingblades called cuts are bolted or otherwise fastened into apoll, forbushing or cutting granite; and the objects of my invention are, first,to fasten any number of cuts into the poll, in such a manner that theymay be securely held, without working loose or breaking; second, tosecure the cuts in the poll with a bolt or bolts and side plates, inconnection with gibs formed on the poll, in such a way as to obviate thenecessity of boring holes through the cuts, wedging, dovetailing, orcutting them away in any manner. 7

' Figure l, is a front view, Fig. 2, a side view, Fig. 3, a sectionalView, Fig. 4, an end view, and Fig. 5, shows the side plates inperspective, of the surfacer bush-hammer. Fig. 1*, is a front view, Fig.2 a side view, Fig. 3*, a sectional view, Fig. 4,, an end view, and Fig.5 shows the side plates in perspective, of the hand bush-hammer.

The poll, E, is made with gibs, D, on the sides and ends, the sideplates, C, fit into the gibs formed on the sides of the poll, the bolt,B, passes through the side plates and poll, but not through the cuts, A,which are fitted into the aws formed by the side plates and the endgibs, onthe poll, the bolt is then tightened up, holding the cutssecurely in place.

I am aware that prior to my invention, bush-hammers'have been made, withthe cuts held in a poll by bolts;

I therefore do not claim such a combination broadly, but

I claim;

The combination in a bush-hammer, of a poll, having gibs formed on itssides and ends, with a bolt hole or holes through the poll and sideplates, but not through the cuts; the side plates and cuts fitting intospecially constructed gibs on the poll, and with the bolts, holding thecuts firmly in place; all substantially as shown and described.
